ATTACHMENT FOR RENDERING BOTTLES NON-REFILLABLE.

Application filed January 10, 1916.

To all whom it may concern Be it known that I, REGINA U. SMITH, a citizen of the United States, and a resident of the city of Portland, Multnomah county, State of Oregon, have invented a new and useful Improvement in Attachments for Rendering Bottles Non-Refillable, of which the following is a specification.

This invention relates generally to nonrefillable bottles, and has particularly to do with an improved attachment adapted for use with a standard form of bottle. By the use of this attachment, the bottle is rendered proof against being refilled until the attachment has been removed.

One of the main objects ofmy invention is to provide a bottle attachment which will be of simple and inexpensive construction, efficient in action, and which may be adapted for use with any type of bottle.

In the accompanying drawings: Figure 1 is a vertical, sectional view of a bottle containing liquid, and showing my improved atachment as used in connection therewith.

The broken lines of this figure illustrate the positions assumed by certain parts of the attachment when the bottle is upturned for the purpose of pouring liquid from the bottle; and Fig. 2is a fragmental elevation showing the means by which my device is locked and sealed in position on the bottle.

In the drawings, (t represents a bottle of standard form, of which I) is the neck and c is the enlarged head at the extremity of the neck. This bottle contains a liquid (Z, and the action of my attachment is such as to permit the pouring of the liquid from the bottle, and at the same time prevent the repouring of any liquid into the bottle.

A flexible nipple e, of rubber or other suitable material, is provided with a reinforcing ring, 7, around its upper end. Said ring is secured to the nipple by cementitious means or any other suitable means, and the purpose of this ring is to form a rigid seat for a closure 9. Said closure 9 is securely attached to the ring so as to form a permanent partial closure for the end of the nipple. Said closure is provided with a spring flap h, adapted to normally close over the outlet orifice of the nipple, due to the inherent resilient qualities of the flap, but will readily open under the slight pressure exerted against the under side of the valve in pouring out the contents of the bottle. The nipple e is further provided with a re Specification of Letters Patent.

be refilled by an authorized person.

The upper end of the nipple is further provided with a weight j, fixed on one side, and when the bottle is in normal upright position said weight will cause the nipple to assume the position shown in the full lines of Fig. 1. \Vhen in this position the body of the nipple will collapse and form a liquid seal as indicatedby k.

A housing m is made with a neck a, adapted to receivea cork 0, and a reduced, expansible lower end 79, provided with an annular rib Q and longitudinal slots 1'. This construction permits the housing to be placed in position over the nipple and the neck of the bottle.

I A spring clamp sleeve 8, provided with a flaring collar t and companion flanges a, is adapted to be placed around the reduced end p of the housing, above the rib (1. When in this position the flanges u are connected by a small bolt o, and a sealed wire to, ininserted through a hole in said bolt, outside of the nut :0, prevents the removal of the latter without breaking the seal.

In the body of the housing m, at the base of the neck n, is a lateral fixed diaphragm 9/ provided with a central orifice 2. Rigidly supported above the diaphragm y, and spaced therefrom by the rivets 2, is a circular diaphragm 3, which entirely overlies the orifice a. The periphery of the diaphragm 3 is spaced from the walls of the housing, so as to permit a free passage of liquid in the path indicated by the arrows in Fig. 1.

It will thus be seen that when the parts are assembled in the position shown, the nip ple is inaccessible, although a free passage is offered for out-flowing liquid. However, it will be impossible to refill the bottle until the housing has been removed.

In special construction, the housing may be permanently attached to the bottle, as by cementing it on, in which case the bottle may be used only once.

I claim:

1. In a device of the character described, the combination with a bottle, of a flexible nipple adapted for attachment to the neck of said bottle, a spring checkvalve closure for the end of said nipple, and a weight attached to one side of said nipple.

2. In a device of the character described, the combination with a bottle, of a flexible nipple adapted for attachment to the neck of said bottle, a check-valve closure for the end of said nipple, a weight attached to one side of said nipple, and an enlarged body encompassing said nipple adapted for engagement with the neck of the bottle.

3. In a device of the character described, the combination of a nipple made of flexible material adapted for being affixed over the neck of a bottle, means for holding the dis charge end of the nipple in expanded state, such discharge end being partially closed, and an outwardly openable valve closing the remainder of the opening of said discharge end, such valve adapted to yield to pressure exerted against its inner side.

4c. In ,a device of the character described, the combination of a nipple made of flexible material adapted for being afiixed over the neck of a bottle and including a portion extending substantial distance beyond the mouth of the bottle, means for holding the discharge end of the nipple in expanded state, such discharge end being partially closed, an outwardly openable valve closing the remainder of the opening of said discharge end, such valve adapted to yield to pressure exerted against its inner side, and

an annular member adapted for being atiixed over the base of the nipple, when the latter is afiixed on the neck of a bottle, for thereby supporting the base of the nipple some distance beyond the mouth of the bottle and causing the upper part of the nipple normally to overhang said annular member at one side in a collapsed state.

5. In a device of the character described, the combination of a nipple made of flexible material adapted for being aflixed over the neck of a bottle and including a portion extending a substantial distance beyond the mouth of the bottle, means for holding the discharge end of the nipple in expanded state, such discharge end being partially closed, an outwardly openable valve closing the remainder of the opening of said discharge end, such valve adapted to yield to pressure exerted against its inner side, an annular member adapted for being aiiixed over the base of the nipple, when the latter is affixed on the neck of a bottle, for

thereby supporting the base of the nipple some distance beyond the mouth of the bottle and causing the upper part of the nipple normally to overhang said annular member at one side, in a collapsed state, and a supplemental neck, also adapted for being affixed to the neck of the bottle, having a lateral annular enlargement accommodating said upper part or" the nipple both in its pendent and collapsed state.
